CHURN.

Specification of Letters Patent.

Patented March 2, 1909.

Application filed. June 30, 1908. Serial No. 141,121.

T 0 all whom it may concern:

Be it known that I, Lnwis An'rnun bnrrit,

a. citizen of the'United States, residing at Seaton, 1n the county of Mercer and State of Illinois. have invented certain new and useful Improvements in Churns, of which the l atcly of one of the standards 10 and 18 profollowing is aspecification.

This invention relates to churns and has I especial reference to a churn which is mechanically operated.

An object of this invention is to produce a churn which is so operated as to have its opposite ends alternately raised and lowered its free end with outwardly turned lips 21-.

to produce the desired result.

Another object is to construct a churn of this character which operated.

the provision of a cover of special con struction which is hermetically sealed when applied and which may be removed easily.

A still further object of this invention is the provision of means whereby the churn may be released from the operative mechanism in order to tiil the churn or to remove the contents therefrom.

Other objects and advantages will be apparent from the following description and it will be understood that changes in the specific structure shown and described may be made Within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a portion of this specification and in which like numerals of reference indicate similar parts in the several views, Figure 1 is aside elevation of the complete device Fig. 2 is an end elevation showing the operative mechanism, Fig. 3 is an opposite end view of the same, Fig. fl: is a side elevation showing the churn in section.

Referring now more particularly to the drawings 10 designates four standards which are vertically disposed in pairs and are provided upon their lower extremities with supporting feet 11. The members 11 are preferably of arcuate formation and are disposed transversely across the lower ends of the standards 10. F or the purpose of holding the standards 10 in rigid position braces 12 are employed which extend between the standards 10 and have their extremities secured intermediately of the standards 10.

Journaled in the upper ends of the standmay be manually lar member 26. The invention has for its still further obl i i l i l i l i i i l i i i i r l 'material within the receptacle 15 a ards 10 are two cross shafts 1 3 and 14 which are adapted to support the churn 15. The shaft 1-lis provided upon one end with a pinion 16 which is adapted to mesh with 2 gear 17 carried upon a counter shaft 18. The counter shaft 18 is mounted intern'iedividcd upon its outer extremity with a crank arm 19. The crank shaft 1 1 carries intermediate of its length a sleeve 21 which is provided with an upwardly extending arm :12 which supports a semi-circular engaging member 2 3. The member 23 is provided at which are adapted to support and carry the (nitwardly turned lips of a second circu- The members 23 and 26 form a clamp member which is adapted to support one end of the churn 15 in operative position. At one side of the clamping member the lips 21!: and are hinged while at the opposite side a detachable clamping screw is provided upon the upper lip 25 which is adapted to extend therethrough and to engage the under lip 2-1. The arm 22 is rigidly carried upon the member 23 and is held in a vertical position.

The crank shaft 13 supports a circular member 27 through the medium of a sleeve 30 and a rigidly secured arm 29. The semi.- eircular member 27 supports upon its upper free end a semi-circular member 28, the whole forming a second clamping member to be secured to the opposite end of the churn 15.

The churn or receptacle 15 is of the ordinary construction of a barrel with the exception of the removable cover and means for securing the same at one end. The receptacle 15 is provided with an upwardly extending flange 31 around its open end which is provided with external threads A annulus 33 is adapted to be placed upon the upper end of the flange 31, the annulus 33 being preferably formed of cork or a like compressible material. A large cover 3-1 is adapted to be placed over the opening and secured thereto by means of a depending flange 35. In the upper side of the receptacle 15 an aperture is formed therein in which is placed a section of transparent material 36, of glass or the like, to enable the operator to ascertain the condition of the different stages of the operation thereof. The receptacle 15 also carries in its upper side a plug 37 which closes an air vent which is adapted to be opened at times to admit air to the interior of the receptacle 15.

The operation of the device is as follows: The receptacle 15 is disengaged from the clamping members 23 and 26 and 2'? and 28 and placed in an upright position. The cover 34 is then disengaged from the flange 31 and the material is placed within the churn 15. After the cover 34 is secured in position the members 26 and 28 are swung backwardly upon their pivot points and the churn 15 is horizontally disposed upon the members 23 and 27. The members 26 and 28 are then drawn down over the churn 15 and clamped in position. The operator now grasps the hand piece 20 and operates the crank 19. The gear 17 being thus revolved the pinion 16 is caused to rotate and carry the crank shaft 14:. Through the medium of the sleeves 21 and 30 the arms 22 and 29 are caused to eflect a circular motion and to impart the same to the churn 15. The gears are so formed that the gear 16 is adapted to turn three times to each revolution of the gear 17.

What is claimed is:

1. A device of the class described comprising a frame, crank shafts mounted in said frame, clamping members carried by said crank shafts, operative means positioned at one extremity of one of said crank shafts,

a receptacle adapted to be engaged by said clamping members, said receptacle having two apertures formed in the upper side thereof one of said apertures adapted to be closed at times by a plug, transparent plate adapted to close the other of said apertures, an upwardly extending iange from one end of said receptacle, a cover adapted to engage over said flange at times, an annulus formed of compressible material adapted to be positioned upon the upper edge of said flange.

2. In a device of the character described the combination of standards, feet carried by said standards, crank shafts disposed in the upper ends of said standards, sleeves carried upon said crank shafts, upwardly projecting arms on said sleeves, clamping members carried upon said arms, a receptacle horizontally positioned in said clamping members, a pinion carried on the extremity of one of said crank shafts, a gear meshed with said pinion mounted upon a stub shaft on the outer face of one of said standards, and a crank arm on said stub shaft for actuating said gear.

In testimony whereof I aflix my signature, in presence of two Witnesses.
